170whp is kinda ***** though man.
Well I used to have a 97 Miata with MSPNP and a Series 3 BEGI GT2860RS Turbo setup, so i'm not entirely new to this. Given it was fast, i'm not ready to shell out another 4,000 dollars for a fast *** stand-alone turbo system... I am very well pleased with what I have right now though
For less than 900 dollars, I am running a 170rwhp MSM setup. At this horsepower, I don't even have to replace my stock clutch that has 49,000 miles of use on it. It's more of a matter of cost than power for me. 900 dollars got me a great running turbo system which included a brand new IHI turbocharger on top of that. It's pretty affordable to turbo a Miata...up to 8psi, then cost starts going through the roof. I did the 305cc injector swap, didn't do much of nothing since timing is my limiting factor. (I can only retard 4 degrees max) So, pretty much if I want to run anything over 200 rwhp, then i'll have to be prepared to spend anywhere from 1,500 to 2,500 dollars in engine management such as Xede or Hydra, as well as purchase a stronger clutch, and a LC-1 wideband if I get were to buy the Xede.`
Best thing about this Mazdaspeed swap into my 99 10th Anniversary is this, I bypassed the shitty 04/05 MSM ECU and its boost control solenoid. The IHI turbocharger that I have is wastegated at 7-8 psi and it holds steadily with no boost creep, plus I got a 7200 RPM rev limiter and a 99-2000 ecu thats much much easier to work with.
So far i'm really impressed with the driviability. I haven't had any problems with the factory recirculating bypass valve. (it seems to be an issue with alot of MSM's) and the use of a t-bolt clamp puts an end to the notorious throttle inlet blowoff) Flyin Miata's Voodoo Box with 2 degrees of static retard works awesome with my kit. True, I might not have programmable timing, but considering my fuel management and slotted timing wheel cost only 195 dollars, it was a good compromise that saved me alot of money.
I paid 260 for a new turbo, I paid 225 for all the chargepipes, inlet pieces, bypass valve, manifold, outlet, of which I sold the factory intercooler and assorted pieces for 60 dollars and used that to buy a 28x7x2.5 intercooler. Then the voodoo box was 195... Yeah I came out cheap
It was around 800 dollars... I love it! You can barely hear the turbo and the obnoxious woosh sound of a bypass valve is almost inexistent...
